s'tantially 'on the line in Fig. 6, looking in 1he direction of the arrows, andlig. 8 illus- 4rates side and end views, enlarged, of the mandrel.

A ln "the accompanying drawings, in which similar numerals of reference indicate corresponding parte in the several views, the nluneral. l indicaee a Sniable freine shown provided with standards 2, 3, e, which parte may be of any Suitable construction. The Standards :2, 3, have suitable bearings 5, G, in which a hollow shaft 7 is journaled, which shaft is Shown provided with a sprocket wheel S receiving chain 9 which passes over a Sprocket wheel 10 carried by a shaft? 1l iournaled in suiiable bearings Supported by frame 1 for rotating shaft collar 7a 'Secured on Shaft Z limits its endwise nioveinenf. VViliiu shaftA 7 is a rod or bar l2 shown supported near opposite ends of said shaft hyv suiable bearings 13 within said shaft", whereby fhe rod or bar l2 may he supported without rotation. rlhe rod or bar l2 is held in the desired stationary posifion by suiiable means. yForthis purpose ll have shown an arm 1l secured to rod 12 byv Said rod or may be made separate therefrom f and' attached here'o 'asv by a )in 20, so that eheft 7 will rotaie roncentricully with respect to he mandrel. Shaft 7 carries a reel, Spool or support 2l for a ei'rip 22, Such as. paper or liber, that is lo be wound upon the mandrel, and for this purpose l here shown u collar orsleove Q3 secured upon shaflf 7 and having lugs 2l adjuslably Sup porting an arm Q5. ae by means of screw QG,

which arm carries a sindA 27 upon which or he like on stud Qi' Serving to removably support reel Zinnen sind 27, and to permit spiral form at the desired pitch. Mounted eoncentrically and freely yaround mandrel 19 is a guide 30 whose outer endis made in spiral or Wormlike form, being shown provided with a spirally disposed flange 31, shown passing nearly but not Wholly around the tubular portion 30@ of the guide, providing va space 31a for the passage of strip 22 (see Fig. 6). The tubular portion 30a of the guide receives the mandrel and said 'guide is rotated around themandrel simultaneously withand atvthe saine speed as shaft 7 and for this purpose I have shown guide 30 secured by screw 33",*.to a colla-r or cap 33 that is secured `upon shaft 7, as by screw 34. A finger 32 secured to collar 33 projects along part 30a of guide 30 provid-- ing a space therebetween receiving strip 22 to'hold the same in position respecting guide 30. At35 is a suitable counterweight carried by sleeve 23 for balancing reel 21.

lith the arrangements above described the strip 22 is laid upon the mandrel and passed through the snace 31a of guide 30,

respect to mandrel 19. Shaft 37 and thereby reel 40, is rotated to carry said reel around mandrel 19, and in the arrangement shown said reel travels in the direction reverse to the direction of rotation of rel 211 For this purpose Ihave shown shaft 37 p1 `vided with a sprocket Wheel 47 receiving a chain 48 from a sprocket Wheel 49 on a shaft 50 journaled in suitable bearings on frame 1 and carrying a gear 51 that meshes With a gear 52 on shaft 11, fast and loose pulleys 53, 54 on shaft 50 serving to permit suitable rotation of the latter. The arrangement of gearingshown is such that when shaft 50 is rotated in a given direction the reel 40 will be carried around the mandrel in one direction and reel 21 Will be carried around the mandrel in the reverse direction. A suitable counterweight may be 'attached to sleeve 38 on the side opposite reel 40 to balance the latter. rllhe bore 37a in shaft 37 is alined with mandrel 19, as shown in Fig.

and thereupon as reel 21 and its strip are carried around the stationary mandrel coincidently with the simultaneous rotation of guide 30 at the same speed as the reel, the strip will be wound around the "mandrel, passing through the space 31a of theA guide, and the rotation of said guide around the mandrel in contact with the adjacent edge of strip 22 Will cause the spirally Wound be portion of tube 22a to be pushed along the mandrel coincidently with the Winding of the strip thereon in tubular form,so that the strip is pushed along the mandrel at the same relative speed with Which it is wound on the mandrel, and the edges of the convolutions of the strip aline.

I have also shown means for winding a strip or tape 36 around the spirally wound tube 22a while the latter is upon the mandrel, and to this end I have shown the standard 4 provided with a bearing 4a in which is journaled a suitable hollow shaft 37 that carries at its inner end a sleeve or head 38 shown secured to said shaft by screw 39, which sleeve supports the reel 40 of strip 36, for which purpose I have Shown sleeve 38 provided with lug 41 adjustably supporting an arm 42 and carrying at its outer end the spindle or stud 43 upon which reel 40 rotates, said -arm being shown adjustably connected with lugs 41 by screw 44, and spindle 43 is shown carried by a bearing 45 adjustably connected with a'rm 42 by a screw 46, wherebyreel 40 can be supported and adjusted nsuitable angular' relation with 5, for the passage of tube 22".

Mandrel 19,'is shown in polygonal form (Fig. 8), beyond guide 30 and provided with longitudinally disposed sharp edges 19a formed by longitudinal undercut grooves 19b eutor formed in the mandrel, and said mandrel lis preferably tapered toward its outer" end, vall whereby when strip 22 is wound on the mandrel the edges 19a will engage the strip and thereby keep the spiral wind- 'ing or tube 22l from rotating around the mandrel, and thereby the tube 22b will pass from the mandrel in a straight condition and kinks are thus prevented from forming in tube 22).

After the spirally wound tube 22LL has Y .11 formed upon mandrel' 19 for a suitable distance, the strip or tape 36 is laid around said tube, and then both reels are simultaneously revolved around the mandrel in opposite directions, whereby as tube'22ZL is formed and pushed along the mandrel by guide 30vthe strip 3G will be wound around said tube, the resulting tube 22b comprising a plurality of reversely wound spiral strips, the outer strip 3G overlapping the joints between the abutting edges of the strip forming tube 22a. I have also illustrated the strip or tape 36 being Wider than strip 22, whereby the edges of the latter may overlap as desired in accordance with the`inclination of reel 40 with respect to the axis of the mandrel. The tube 221.j thus formed passes through the bore 37El of shaft 37.

Strip 22 may be of paper or fiber while strip 36 may be of fabric or friction tape, and the finished tube may be used for a conduit to receive electric conductors, preferably provided with a covering in manner.
